Me! However, we have a solution!
Kudos to James for forwarding this link on to me - it's actually an incredibly nifty, and useful tool!
The Virtualisation (ok, Virtualization for those in the US) Calculator comes in 2 flavours, namely, Calculator 1 and Calculator 2 (Sorry, couldn't resist) and thus provide two ways to estimate the number and cost of Windows Server Standard Edition, Enterprise Edition and Datacenter Edition licenses needed for your virtualisation scenarios to help you determine the most cost-effective edition of Windows Server.
The calculators, at present, don't cover Windows Server 2008 and Windows Server Virtualisation, but, unless the licensing changes dramatically, you should still be able to get a good idea of the pricing, but they are aimed at Windows Server 2003.
So, how do the calculators differ? Well, in a nutshell, Calculator 1 is an interactive, flash-driven experience, which, in my opinion, is a bit easier to use than Calculator 2, which is more of a print-out and complete wall-chart. Calculator 1 "lets you interactively build virtual machines running multiple Microsoft server products to estimate the licenses and costs for Windows Server by edition (Standard, Enterprise and Datacenter) and many Microsoft server products. It starts with configuring your server based on virtualization technology, sockets and clustering requirements, and then builds the virtual machines."
Now, one of the great things about Calculator 1 is it also takes other 3rd Party Virtualisation solutions into account, because, let's face it, not everyone is building solutions on Virtual Server, so it's important that we provide licensing information for these scenario's too.
Once you've run through the scenario's in Calculator 1, you can export your results into Excel, or alternatively, print them out.
If you are unsure about licensing in a virtual environment, or want to understand pricing more effectively, this would be a great place to start.

I'm going to start with a statement that will probably resonate with a lot of you out there; Licensing
